Correct option is D

The age at first calving in Murrah Buffaloes, a breed known for its high milk production, is typically in the range of 40-42 months. Studies show that Murrah Buffaloes usually give their first calf between 40 and 42 months of age.
The delayed age at first calving allows the buffalo to reach sufficient maturity and body size before entering the reproductive phase. This is important for the overall health and reproductive performance of the animal.
